the deep

8:31the deep. The “deep” (Greek abussos, ‘without bottom’) is the “bottomless pit” (Revelation 20:1,3) at the center of the earth, where many of “the angels that sinned” (II Peter 2:4) in the pre-Flood world had already been bound. Note also the parallel accounts in Matthew 8:28-34 and Mark 5:1-17.
